On my top destinations in north Europe is Iceland. Such a beautiful place to visit. In Iceland, you can visit all tourist attractions, which maintain the original natural appearance, for free. Following are some of its attractions.
Akureyri,which has the nickname of the Capital of North Iceland, is a small but memorable urban city in northern Iceland. Climbing is a very suitable activity in summer in Akureyri (for there is only snow on the mountain in winter).
Jökulsárlón is a large glacial lack in southeast Iceland, on the edge of Vatnajökull National Park. Titanic and Game of Thrones(S2) was shot here. In the lake is full of floating iceberg existing since Ice Age. Icebergs are all pure and blue, and blue becomes darker when the iceberg turns larger.
Dettifoss is a waterfall in Vatnajökull National Park in Northeast Iceland, and is reputed to be the most powerful waterfall in Europe. Standing by the waterfall, you can be totally shocked by the power of nature (although the progress to get there can be really difficult)
Vík is the southernmost village in Iceland, located on the main ring road around the island. For the sand is made up of cinerite, the beach is black. Climbing on to the cliff, you can see almost the whole village.
